ACTUAT ING MECHANISM FOR WASHING-lllIAdHINES.

To aZZ whom it may concern:

a citizen of the United States of America, and a resident of Waterloo,Blackhawk county, Iowa, have invented certain new and usefulImprovements in Actuating Mechanism for fishing-Machines, of which thefollowing is a specification.

My invention relates to improvements in' actuating mechanism for washingmachines or the like, and the object of'my improvement is to provide asimple, inex ensive and easily operative mechanism or imparting asimultaneous rocking and translator'y movement to a plunger-rod, withoutbinding or complexity ofparts, or difficulty in repair. This object Ihave accomplished by themechanism which is hereinafter described andclaimed, and which is illustrated in the accompanying drawings, inwhich: Figure l is an end elevation of my said mechanism as applied tothe tub of a washing machine, said tub being vertically and centrallysectioned and partly broken away. Fig. 2 is a detail side elevation ofmy improved actuating mechanism. Fig. 3 is a detail perspective view ofthe conjoint swiveled and hinged connection between the crank arm andthe slide-bar of my device.

Fig. 1 is another perspective detail of the parts shown in Fig. 3, buttaken from another point of view. Fig. 5 is an enlarged horizontalsection through the plunger-rod and its sleeve-bearing for saidslide-bar, and

also through the crank-arm at the location of its swiveled connection tosaid slide-bar.

Similar numerals of reference denote corresponding parts throughout theseveral views.

My improved actuating mechanism for imparting simultaneous translatoryand rocking movements to a plunger-body, is shown as applied to use inoperating a washing-machine, but it is obvious that said mechanism maybe applied to any other use desired.

The numeral 5 denotes the tub of a washing-machine, having a hingedcover on whose top is centrally mounted a bearingbody 4- whieh hasspaced apart bearings for avertical plunger-rod 1, the lower end. ofsaid rod within said tub having a plun ger-head (5 secured thereon.Secured upon.

said plunger-rod above said cover is a sleeve l end swiveied toSpecification of Letters Patent.

jeetions, and said rod, sleeve and its projections are horizontallytransversely orificed in line to provide a continuous and relativelylong bearing-seat for the horizontal slide-bar 3, which last is movabletheret-hrough but never entirely leaves its seat. Mounted also upon saidcover 15 are the standards 11 with integral bearings at their upper endsfor a crank-shaft 9, which last has thereon a fly-Wheel 10 provided witha crank-handle for manual operation. The inner end of said shaft has acrank 8 orificed transversely to rotatably receive the cylindricalconnecting body 7, as a swivel, said part 7 having a fork connected by apintle 13 on which one end of the slide-bar 3 is hinged pivotally. Thesleeve 2 is secured on the plunger-rod l by means of machine-screws 14or other suitable means. It will be observed that the upper part of theslidebar 3 isfiattened at- 12, this flattened part fits a similarflattened part of the wall of the bearing in the sleeve 2 and rod 1,

andv prevents the bar 3 from turning.

To operate the device, theshaft 9 is rotated by the means shown orotherwise, to rotate the crank S, and the crank carries about the pin onthe body 7, rotating relatively to said pin, while the body 7, its hingeto the slide-bar 3 and said bar 3 remain horizontal and withoutrotating. Since the slide-bar 3 is carried about by said crank, itsouter hinged end swings to cause the inner end to raise and lower theplunger-rod 1, and the said bar 3 simultaneously slides hack and forthhorizontally through its seat nrthe bearing orifice in the rod 1 and itsslee\\e 2. In sosliding to and fro the said bar-3 imparts a rockingmovement to said plunger-rod; Thus a simultaneous translator-y androcking movement is impressed upon said rod.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is:

1. In combination, a plunger-rod having a transverse orifice, abcaringior sa d rod, and means adapted to actuate said rod. comprising arotary cranl left, a bar slidable through the orifice in said rodnecting body havin adjacent end of 2. In combination, a plunger-rod, asleeve secured thereon and having integral oppo sitely-directed parts,said parts, the sleeve and the rod being transversely orificed, aslide-bar slidably mounted in the seat in said parts, a rotarywank-shaft, and a body finged to one end of said slide-bar and swiveledt0 the crank on said shaft, and l adapted to impart simultaneoustranslatory and rockmg movements to said plunger-rod. 19
